Well, if you sent a request to a web server, it is obviously gong to know that you requested something from it- so in general it should be the expectation of a user that the server owner has a reliable way to track that activity.
Tracking pixels, cookies, etc that follow a user around the web and gather activity that someone did NOT send to a server and relay it back to said server is IMHO spying.
Just because it’s being served into the browser on each payload doesn’t mean it was requested or desired.
All those things you named are spyware, marketed under the guise of diagnostic reporting. And, to be fair, that most certainly are also used for diagnostic purposes. But that’s not how they make money.
